Our Technical Preview Program allows you — our dedicated QNAP NAS fans — the chance to be the first to try Technical Preview of QTS 4.2. The feedback you provide on quality and usability will help us identify issues, fix them, and make QNAP NAS even better. Apply via the link below to join our Technical Preview Program.

Please note that since the preview edition has not yet been commercially released by QNAP, it may contain errors or inaccuracies and may result in data loss or cause issues of system reliability. If such problems arise, you may need to reinitialize your system to resume normal operation.
